The term Weatherproof can be misleading
This product in general works well, easy to install and fitted securely to the roof rack which gave peace of mind when driving. I gave this item a 4* rating based on the item itself my only real criticism is the way it is decribed under product attributes. Please be aware of the term 'weather proof' does not necessarily mean waterproof , it does not even mean 'water/rain resistant '. If you intend purchasing this item for use over longer distances with the possibility of inclement weather i.e rain , I would not recommend it , this bag will NOT keep your stuff dry!
